x402
Spoofability Check Watch is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).
Monitors a domain's email spoofability (SPF + DMARC) over time and returns whether the result has changed since the last call, with before/after field diffs.

How this service works
Change watch for spoofability check: runs the check and compares it with the result from your previous call for the same domain (kept 90 days), returning the current answer, changed true/false, exactly which fields changed with before/after values, and when it was last seen. Call it on a schedule to be told when can this domain be spoofed? checks whether spf and dmarc together actually block forged mail changes. $0.01 per check.
Output
Returns the current spoofability answer (can the domain be spoofed: yes/no), a boolean 'changed' flag indicating if the result differs from the previous call, a detailed diff of exactly which fields changed with their before and after values, and a timestamp of when the previous result was last seen. Previous results are retained for 90 days.
Example use cases
Alert on domain spoofability regression
“Set up a scheduled check on acmecorp.com — run the spoofability watch every day and ping me immediately if the result changes, telling me which fields changed and whether the domain is now spoofable when it wasn't before.”
Post-deployment email security audit
“We just updated our DMARC policy on mybrand.com — run the spoofability watch check now and tell me if our changes actually made a difference compared to the last result, with the before and after field values.”
Third-party vendor domain monitoring
“I need to keep tabs on whether our payment processor's domain, vendorpay.io, becomes spoofable over time — run the watch check on it and report any change in spoofability status or underlying SPF/DMARC fields since the last check.”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/watch/email/spoofableWhen to prefer
Choose this endpoint when you need to detect changes in email spoofability over time rather than just a one-off check. It is ideal for scheduled monitoring workflows where you want to be alerted only when the spoofability status or underlying SPF/DMARC configuration actually changes, avoiding noise from repeated identical results. Prefer it over a simple spoofability check when diff tracking and change history matter.
Side effects
- Domain not previously checked — no prior result to compare against, diff will be empty
- Domain does not exist or has no DNS records — check may return error or inconclusive
- SPF/DMARC records temporarily unavailable due to DNS propagation delays
- Previous result expired (older than 90 days) — treated as first call with no diff
- Rate limiting or payment failure via x402 protocol
